Once the decision for surgery is made, the focus shifts to the specific procedural technique and the biological healing process. Treatment is tailored to the anatomy; a nerve that snaps requires a different surgery than a nerve that is simply squeezed.
The surgical suite is equipped with microsurgical instruments to handle the delicate nerve tissue. Whether decompressed or transposed, the nerve requires a period of protected healing to recover its blood supply and axonal flow.
Recovery is a balance between protection and mobilization. Immobilizing the elbow too long leads to stiffness, while moving too soon can stress the healing tissues. Protocols are designed to navigate this narrow path to optimal function.
This is the standard procedure for fixed compression without subluxation. An incision is made along the inside of the elbow. The surgeon identifies Osborne’s ligament and carefully divides it.
This releases the roof of the tunnel. The surgeon also checks for tight bands above and below the elbow (Arcade of Struthers). The nerve is left in its natural groove. This preserves the small blood vessels feeding the nerve, which is a major advantage for healing.
If the nerve is unstable and snaps over the bone, it must be moved. In a subcutaneous transposition, the nerve is freed from its groove and moved to the front of the elbow.
A sling is created using a flap of fascia from the flexor muscles. This sling keeps the nerve from sliding back behind the bone. The nerve sits just under the skin and fat. This relieves tension on the nerve during flexion and prevents the snapping sensation.
This is the most robust protection for the nerve. After moving the nerve to the front, the surgeon lifts the flexor muscle mass and places the nerve underneath it. Alternatively, a channel is cut into the muscle.
The nerve is now buried deep under muscle. This provides a vascular bed for healing and protects the nerve from direct trauma. This technique is often preferred for very thin patients, revision surgeries, or athletes who risk direct blows to the elbow.
This minimally invasive approach uses a small scope. A tiny incision is made, and a clear cannula is inserted along the nerve path. The camera allows the surgeon to see the constricting bands from the inside.
A retractable knife is used to cut the ligament. This technique results in a much smaller scar and less dissection of the surrounding tissues. It is an excellent option for uncomplicated compression but cannot be used if the nerve needs to be moved.
Instead of moving the nerve, the surgeon removes the bone that the nerve rubs against. The medial epicondyle is exposed, and an osteotome or saw is used to remove a portion of the bone.
This creates a smooth, flat surface. The nerve can now slide forward without catching on the bony prominence. This procedure avoids the extensive dissection required for transposition but carries a risk of medial elbow instability if too much bone (and ligament attachment) is removed.
Most surgeries are done under general anesthesia with a laryngeal mask airway. Alternatively, regional anesthesia (axillary block) can numb the entire arm, allowing the patient to remain awake but sedated.
The patient is positioned supine with the arm on a hand table. A tourniquet is applied to the upper arm to provide a bloodless surgical field. This visualization is critical to avoid damaging the tiny branches of the nerve.
After the procedure, the layers of tissue are closed carefully. If the nerve was transposed, the fascia is closed loosely to ensure it doesn’t compress the nerve in its new home.
Absorbable sutures are typically used for the skin. A bulky soft dressing is applied from the hand to the upper arm. This acts as a splint, restricting elbow movement for the first few days to allow the wound to settle and prevent hematoma.
Pain is usually managed with oral analgesics and NSAIDs. Patients are instructed to keep the hand elevated above heart level to reduce throbbing and swelling.
Finger motion is encouraged immediately to prevent stiffness and reduce edema. The bulky dressing is usually removed after 3 to 5 days, replaced by a lighter dressing or a removable splint depending on the procedure performed.
Nerve recovery is slow. The nerve fibers regenerate at a rate of approximately 1 millimeter per day (about an inch per month). Therefore, relief of numbness in the fingers can take months.
Pain relief at the elbow is often immediate. Sensation returns first, followed by motor strength. If the muscle atrophy was severe, recovery may be incomplete. Patients are counseled that the primary goal is to stop progression, with recovery being a bonus.
Potential complications include infection, hematoma, or injury to the medial antebrachial cutaneous nerve (causing numb skin on the forearm).
A specific complication of transposition is the nerve becoming stuck in scar tissue again. If symptoms return, revision surgery may be needed. Complex regional pain syndrome (CRPS) is a rare but serious reaction that requires aggressive pain management therapy.

No, you cannot drive immediately after surgery. You will have had anesthesia, and your arm will be in a bulky dressing that restricts movement. You must arrange for a responsible adult to drive you home.
For a simple decompression, the splint might be removed in 3 to 5 days. For a submuscular transposition, you might need a splint for 2 to 3 weeks to allow the muscle to heal over the nerve before you start moving the elbow.
Desk work can often be resumed in 1 to 2 weeks. Heavy manual labor, lifting, or jobs requiring repetitive elbow movement may require 6 to 12 weeks off, depending on the type of surgery and the physical demands of the job.
The incision is on the inside of the elbow. It typically heals as a fine white line. Endoscopic surgery leaves a very small scar (1 inch), while transposition requires a longer scar (3 to 4 inches). Scars generally fade significantly over the first year.
Nerves heal very slowly. The part of the nerve that was crushed needs to regrow all the way down to your finger. This takes time. It is normal for numbness to persist for months while the nerve regenerates.
